6.2.5 Piping of remote seal type pressure transmitter (FKB, FKM)
Seal on mounting flange face
When mounting the
fl
ange on the high pressure side, a gasket should be inserted as fol-
lows. The seal must be chosen according type
fl
ange mounted on the transmitter. The
internal diameter must be greater or equal the diaphragm seal to not press it and effect the
measure.
When measuring a highly corrosive process
fl
uid, be carreful about corrosion that may
occur if the
fl
uid leaks past wetted parts.
